In the 1922 Sonora catalog of "Periods" (they weren't called "Art Models"), 19 different designs are illustrated, and appear to be in descending order of features, detail, and presumably price. The William & Mary appears 12th among these 19, so it wasn't one of the more elaborate models. Although the catalog claims its 2-spring motor to be gold-plated, this one isn't. And although the 1922 "Periods" catalog specifies a Motor-Meter, and the instructions claim that an electric light is included, this example has neither of those features. The original Instructions and Index were found with this machine, and it was originally owned by N.J. Hassinger & Family of Batavia, N.Y. This isn't the loudest talking machine I own, but I find it peculiarly sweet-toned. I usually play Fritz Kriesler on it for guests.
Sonora seemed to change cabinet designs often in virtually all its models, and the Periods are no exception. Below, I've included scans from Sonora's 1920 catalog, its 1922 "Periods" catalog, and from its 1924 catalog. You'll notice changes within models.
I'm not sure when Sonora began offering the Period Models, but the company's purchase of the Herzog Art Furniture Company in 1919 must have made it much easier to obtain high-quality cabinetry.
I hope others enjoy this, and if anyone would like a scan of a particular model from the 1922 Sonora "Periods" catalog, I'll be happy to provide it.
